Comparison of satellite models to NGS-held point height-anomalies
- only a statistical comparison may be made because these data are point values
- they highlight 400 km features not well represented in G99SSS as determined by an empirical covariance function
- tidal system is tide-free
- data reference NAD27 & NGVD29 but can be converted to NAD83 & NAVD88
